获取java.sql.SQLException：无效的列名称与休眠

Question

Getting java.sql.SQLException: Invalid column name even though column with same name are in table. what can be a reason?

I am trying to call sp with below code:

 Session session = HibernateUtil.getSessionFactory().openSession();
            Query query = session.getNamedQuery("EMPLOYEE.PRC_HB_EMP_SP1");
                    query.setParameter("IN_EMPID", empId);

              List<Employee> empList = query.list();
              System.out.println(empList);

Entity class Employee:

    @Entity
    @Table(name = "EMPLOYEE")
    //@org.hibernate.annotations.NamedNativeQuery(name = "EMPLOYEE.PRC_HB_EMP_SP1", query = "call PRC_HB_EMP_SP1(?,:IN_EMPID)", callable = true, resultClass = Employee.class)
    @org.hibernate.annotations.NamedNativeQuery(name = "EMPLOYEE.PRC_HB_EMP_SP1", query = "call PRC_HB_EMP_SP1(?,:IN_EMPID)", callable = true, resultClass = Employee.class)

    public class Employee implements Serializable {
    private static final long serialVersionUID = -723583058586873479L;
    @Id
    @Column(name = "EMPID")
    private Integer empId;
    @Column(name = "EMPNAME")
    private String empName;
    @Column(name = "ADDRESS")
    private String empAddress;
    @Column(name = "SALARY")
    private Long salary;
    @Column(name = "EMPAGE")
    private Integer empAge;
............
}

here is sp:

create or replace PROCEDURE PRC_HB_EMP_SP1
(
  Out_value OUT SYS_REFCURSOR,
  IN_EMPID  NUMBER
)
AS

BEGIN

   open Out_value for
    SELECT EMPID,EMPNAME 
            FROM EMPLOYEE
    WHERE  EMPID = IN_EMPID;

END PRC_HB_EMP_SP1;

Answer 1

您的映射包含ADDRESS，SALARY和EMPAGE列，但SP中缺少这些列。您需要在语句中包括这些列。
